En route is a novel bythe French writer Joris-Karl Huysmans and was first published in 1895.
En route is the second book by Huysmans concerning the religious development of the novelist Durtal, who in the first book ('La-bas') experienced depravity and Satanism.
In this book he struggles desperately to find a foothold in the Catholic faith. He is aided by his aesthetic sensitivities and the support of an understanding priest. But it is not until he undertakes a retreat in a Trappist monastery that he achieves depth of spiritual transformation.
